Hydra V6 Remix for BIQU B1

This is a Remix of the Hydra Fan Duct & Tool Change System V6 Edition, modified to fit the BIQU B1.

*** This is only one part that I modified, you will need to get the other unmodified parts from the original thing. ***

The Hydra is one the best performing and most complete fan duct system that I've come across. And as I found the need to attach E3D's Nozzle X to my BIQU B1, I've decided to go all the way and made this remix.

Because of the symmetry of the B1's carriage and hotend, I was able to simply mirror the right side of the Hydra and most of the work is done. The rest is just adding some mounting for the B1's hotend PCB.

I've made 2 versions:

• OG, which mount the hotend PCB at only the top two corners. This version is easier to print and retains more of the original Hydra's look.
• ALT, which mount the hotend PCB at all four corners. This version more challenging to print without support and it is not really that essential, so get this version only if you really want to mount the PCB at all corners.

All of Hydra's fan ducts collection should be compatible, but sadly, the direct drive extruder mount at the top is ALMOST compatible. Because the B1's USB cable is in the way of the top mounting holes, I had to move the holes to make room for the cable.
If you still want to the direct drive mount, you can drill holes to match the new holes, plus a bit of filing may be needed to clear some space for the cable, or wait for a remix ;)

STEP files are included. Please make improvement and happy printing!
